Finds a route from us (payer) to the given target node (payee).

If the payee provided features in their invoice, they should be provided via the payee field in the given RouteParameters::payment_params. Without this, MPP will only be used if the payee’s features are available in the network graph.

Private routing paths between a public node and the target may be included in the payee field of RouteParameters::payment_params.

If some channels aren’t announced, it may be useful to fill in first_hops with the results from ChannelManager::list_usable_channels. If it is filled in, the view of these channels from network_graph will be ignored, and only those in first_hops will be used.

The fees on channels from us to the next hop are ignored as they are assumed to all be equal. However, the enabled/disabled bit on such channels as well as the htlc_minimum_msat / htlc_maximum_msat are checked as they may change based on the receiving node.

Panics

Panics if first_hops contains channels without short_channel_ids; ChannelManager::list_usable_channels will never include such channels.
